For a crystal-clear in-ear signal

Mipro's MI-58RT in-ear monitoring set combines the series' digital transmitter and compact bodypack receiver. The MI-58 system is aimed at musicians who demand clean and transparent monitoring audio, without the artefacts typical for analogue wireless systems: Because the entire signal path is digital, the sound is free of compression or other technical side-effects that can alter or distort it. Similarly, the connection between the transmitter and the receiver is stable and reliable, with a latency of less than 4ms, which is scarcely audible. As the name suggests, the MI-58 series uses the 5.8GHz frequency band, which is free to use without a licence worldwide – another reason the system is so popular in mobile setups, for smaller stages or rehearsal spaces, or in permanently installed setups.

Mipro MI-58RT Digital In-Ear monitoring set

Expressly designed to be easy

The MI-58T is a single-channel transmitter that has been expressly designed for ease-of-use. Selecting the frequency and transmission power is straightforward, with Mipro's proprietary Automatic Channel Targeting technology (ACT) handling synchronisation. The transmitter also offers a range of useful parameters such as switchable input levels, as well as filtering to adjust the audio signal. The combo jacks on the rear allow musicians to connect line and microphone inputs, either as a stereo signal or as a summed mono monitor feed from a single output. It's also possible to transmit a stereo signal in mono, enabling some creative monitoring setups; for instance, two different mono signals can be transmitted at once. Still, the pared-back controls and well-designed menu ensure that it's always clear what's going on, even during a live performance.

Customising the signal

The Mipro MI-58R bodypack is robust and compact – intended for continuous stage use. The receiver comes with a set of in-ear headphones, so that even beginners have everything they need to get started straight out of the box. It's powered by a rechargeable battery and charged using the docking station also included. There are a number of key settings that musicians themselves can adjust on the receiver. Besides volume control, functions include fine-tuning the sound, including optimising the highs and lows to personal preference – this really helps make the most of the system's excellent signal quality. Another feature with a genuine practical benefit is the balance function: When receiving a mono-mix signal, made up for instance of separate vocal and instrument channels, a performer can precisely set the relative level of the two sources.

Mipro E-8S In-Ear Monitors

For everyday life on stage

Musicians and technicians looking for clear, clean IEM audio have an ideal solution in Mipro's MI-58 series. Especially in loud live venues, high-quality in-ear transmission improves the band's cohesion and timing, while reducing the overall on-stage volume. It should be noted that the 5.8GHz frequency band is limited technologically to shorter ranges than (for instance) UHF systems, with the shorter wavelength also increasing its susceptibility to physical obstructions: This means that the MI-58 is perfect for reliable monitoring wherever the distances involved are not unusually long. This isn't to say that the system isn't suited to professional use: Alongside the outstanding digital audio quality, the devices themselves are very well made, and clearly designed for frequent installation and transport. The transmitter can even be fitted in a 19" rack with Mipro's own accessories.

About Mipro

Established in 1995 in Chiayi, Taiwan, by wireless and audio engineer K.C. Chang, Mipro has become a leader in high-quality wireless audio systems. Now run by his son Solomon, the company specialises in wireless microphone systems, portable sound systems, in-ear monitoring solutions, tour guide systems, and camera receivers. In 2014, Mipro Germany GmbH was founded in Hardthausen, near Heilbronn, to enhance customer service and ensure smooth delivery across Germany. Mipro adheres to the latest manufacturing standards and holds top-tier classifications from the Electronics Association. In Germany, the company is TÜV-certified under DIN ISO-9001:2000, a testament to its commitment to quality.

The right connections for every use case

Combining near-effortless setup, crystal-clear signal, and stage-ready construction, the MI-58 is an IEM system that can play to its strengths whatever the setting. The transmitter has a set of versatile connections that enable a variety of monitoring setups: The combo jacks on the rear accept XLR mic cables and 6.3mm instrument lines, either as a stereo signal or as a mono monitor feed. Further flexibility is provided by the system's deliberate modularity – more receivers can be added almost without restrictions, and multiple transmitters can also be linked and controlled as one unit, which is a major benefit for larger rigs or permanent installations. But it's still the performance of the technology itself which is most noteworthy here, with the high-quality, low-latency transmission making it suited for all kinds of signals, including vocals and rhythmically unforgiving instruments like drums. All in all, the Mipro MI-58RT offers a coherent balance of clear audio, straightforward operation, and a well‑implemented wireless platform.

Better sound than any analog Shure or Sennheiser, less latency than Shure Axient
HHHHHHHHH 31.01.2025
I bought it with real concerns about quality for this price, but I was searching for improvements in audio quality, especially when used with KLANG, so I gave it a shot. And it exceeded my expectations by a lot.
The sound quality is much better than any analog system. Way less distortion (almost none) than Shure PSM1000, and stereo separation is way better than in Sennheiser G4. Latency is only 2.2ms, which is less than Shure flagship Axient Digital. So, soundwise it is a huge improvement when compared to even big names which cost several times more.
Now RF part. Please understand, that it is ISM 5.8GHz, which means waves are very short and sensitive to obstacles. This means it will not go well over metal, walls, glass, etc. And preferable it must be in direct line with the antenna. It works fine for 30+ meters. It transmits in several frequencies simultaneously, so that's maybe why it is so stable. However, if RF is compromised it starts sounding like MP3, and the worse it gets - the worse MP3 it sounds. Especially heard in high frequency, it becomes squashed, but it won't lose signal immediately. Before dropping - random beeps are heard, so silence will not come with a surprise. No loud explosive sounds are heard like in other systems.
Already traveled for a few months with those, and overall - musicians are very happy. Even in challenging environments (hotels, industrial buildings) works fine (sometimes changing RF frequency group is needed for better sound quality).
Bodypacks are small, and made of plastic, antennas are integrated inside (which is very good), lithium batteries and chargers are provided, together with quite good headphones.
Rear-to-front antenna rackmount and cable are not included but are a MUST if they will be rack-mounted.
So far super happy with the purchase.

Great quality upgrade to my previous analogue IEMs
Wingee 19.05.2025
Was looking for a cost effective alternative to my budget UHF analogue IEMs and found these. Does exactly what I was looking for: low latency, great sound quality and great build quality. After buying 1, I bought 2 more!

One of My Best Gear Discoveries
marcomartins20 16.01.2026
The Mipro MI-58RT was one of the best discoveries I made last year. It’s a 5.8 GHz system and, after using several other wireless setups, including UHF systems like the Sennheiser G4, it delivers a noticeably cleaner signal in real-world use. This is based on touring experience across more than 200 shows. Rock solid performance, especially if you’re not aiming for mid-tier UHF systems.
